Embodiment Construction

[0011] exist figure 1 In the schematic diagram of the front view section of the heat pipe module heat dissipation oil bath motor shown, the motor stator 2 is arranged in the closed casing 1 of the motor, and the motor rotor 3 corresponding to it is arranged on the motor shaft 4, and the motor shaft wears Through two supporting bearings 5 ​​and an end plate 6 of the housing, it stretches out of the housing. The motor housing between the stator, rotor, shaft and support bearings is filled with cooling oil 7 . The end plate of the housing without the motor shaft passing through is a hole plate 8, and a heat pipe 9 is arranged in each through hole, and the middle part of the heat pipe is fixed and sealed on the end plate by a fixing flange 10. The above-mentioned heat pipe with internal heat transfer working medium has a heat absorbing section located inside the casing, and a heat dissipation section located outside the casing, and fins 11 are arranged on the outside. A protecti...

Abstract

The invention provides a heat-pipe module heat dissipation oil bath electromotor. The electromotor is characterized in that a shell end plate which is not passed by a motor shaft is an orifice plate, a heat pipe is arranged in each through hole, and the middle of each heat pipe is fixed by a connecting piece and sealed on an end plate; heat transmission working substance is arranged in the heat pipe, the heat absorption section of the heat pipe is positioned in the shell, the heat dissipation section is positioned outside of the shell, the shell end plate provided with the heat pipe is provided with a fan; the heat dissipation sections of the heat pipes are externally provided with a protective cover which holds the heat pipes, and a fin, a gill and a spiral piece; and a heat transmission module is fixed on an electromotor shell so as to rapidly emit heat, the normal operation of the electromotor is guaranteed, and particularly a cooling problem of a high power motor is solved.

Description

technical field [0001] The invention relates to an electric motor, especially an electric motor with a heat dissipation mechanism. Background technique [0002] During the operation of the motor, the temperature of the motor will rise due to coil resistance heating and mechanical friction heating, which will reduce the insulation coefficient if it is mild, and will break down the insulation and burn the motor if the temperature exceeds a certain limit in severe cases. In order to make the motor run safely, it is generally to increase the heat dissipation area of ​​the motor casing or cool it through the motor's own fan. Both of these methods appear to be insufficient when the motor power is large. Contents of the invention [0003] The purpose of the patent of the present invention is to provide a heat pipe module heat dissipation oil bath motor which improves the heat dissipation performance of the motor and increases its working load capacity. [0004] The present inve...
